Type: Mineral
Mineral feeds are dissolved minerals your plant can use straight away. They're fast-acting and precise, but it is possible to overdo them, so stick to the dose.

Calcium, Magnesium and Iron in One Bottle

Most indoor plant problems that look like disease are actually missing minerals. Pale new leaves, yellowing between the veins and rusty spots usually point to a shortage of calcium, magnesium or iron.

Essentials PLUS CALMAG supplies all three, plus a little nitrogen, with the iron in two chelated forms so it stays available across a wide pH range.

Why It Works

Calcium: strong cell walls and healthy roots
Magnesium: the centre of every chlorophyll molecule
Chelated iron: EDDHA and DTPA forms for reliable uptake
Nitrogen: supports growth and green colour

For Houseplant & Garden Growers

Watering with rainwater or filtered water, growing under LED lights or using coco? Those are the setups where houseplants run short of calcium and magnesium. A regular dose keeps leaves green.

For Growers

Dose: 1ml per litre alongside your main nutrients
When: during long growth periods, or whenever deficiency shows
EC and pH: CALMAG raises EC, so check it, then check pH after adding and adjust to 5.8–6.5 for hydro and coco

🌿 Rose's Pro-Tip: Add CALMAG to the water first, then your base feed. Minerals in, stir, then nutrients.
